Principal U.S. Mega-Cap ETF - USD Stock

The investment seeks to provide investment results that closely correspond, before expenses, to the performance of the Nasdaq U.S. Mega Cap Select Leaders Index (the 'index'). Under normal circumstances, the fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities that compose the index at the time of purchase. The index uses a quantitative model designed to identify equity securities of companies with the largest market capitalizations in the Nasdaq US 500 Large Cap Index (the 'parent index'), with higher weights given to securities that are less volatile.
